Detailed Description

Propagator based on the Geant4e package. Uses the Propagator class in the TrackingTools/GeomPropagators package to define the interface. See that class for more details.

Constructor & Destructor Documentation

Geant4ePropagator::Geant4ePropagator ( const MagneticField *  field = 0,
std::string  particleName = "mu",
PropagationDirection  dir = alongMomentum 
)

Constructor. Takes as arguments:

  • The magnetic field
  • The particle name whose properties will be used in the propagation. Without the charge, i.e. "mu", "pi", ...
  • The propagation direction. It may be: alongMomentum, oppositeToMomentum
